Preheat your oven to 400°F (200°C).
Wash the yellow squash and zucchini, then slice them into thin rounds, approximately 1/4-inch thick.
Peel and finely dice the yellow onion. Mince the garlic cloves.
Heat a large oven-safe skillet over medium heat and melt the unsalted butter.
Add the diced onion to the skillet and sauté for 2-3 minutes until softened and translucent.
Stir in the minced garlic and cook for another 30 seconds until fragrant.
Add the sliced squash and zucchini to the skillet. Season with salt, pepper, and fresh thyme. Sauté for 5-7 minutes, stirring occasionally, until the vegetables begin to soften.
Pour the heavy cream over the vegetables and stir to coat evenly. Let the mixture simmer gently for 2-3 minutes.
Remove the skillet from the heat and sprinkle the shredded Gruyère cheese evenly over the squash mixture.
In a small bowl, combine the breadcrumbs, shredded Parmesan cheese, and olive oil. Mix until the breadcrumbs are lightly coated.
Evenly sprinkle the breadcrumb mixture on top of the cheese layer in the skillet.
Transfer the skillet to the preheated oven and bake for 12-15 minutes, or until the top is golden brown and bubbling.
Carefully remove the skillet from the oven and let it cool for 5 minutes before serving.
Serve warm and enjoy your creamy, cheesy Skillet Squash Au Gratin!
